BACKGROUND: Healthcare professionals (HCPs) who are physically active are regarded as more likely to act as credible physical activity (PA) role models and promote healthy lifestyles. This study explores PA levels and underlying motivations, within and between HCP students, first testing the validity and reliability of the Behavioral Regulation in Exercise Questionnaire (BREQ-2). METHODS: The International Physical Activity Questionnaire (IPAQ) and BREQ-2 were administered to 296 HCP university students (physiotherapy n = 47, medicine n = 105, nursing n = 121, radiography n = 23)...

The development of neutron imaging from a qualitative inspection tool towards a quantitative technique in materials science has increased the requirements for accuracy significantly. Quantifying the thickness or the density of polycrystalline samples with high accuracy using neutron imaging has two main problems: (i) the scattering from the sample creates artefacts on the image and (ii) there is a lack of specific reference attenuation coefficients. This work presents experimental and simulation results to explain and approach these problems...

INTRODUCTION: Irish diagnostic radiography has undergone significant change with the dual introduction of state registration and mandatory Continuing Professional Development (CPD) in October 2015. We aimed to investigate motivators and barriers around CPD participation, mechanisms of CPD delivery and confidence of radiographers in using e-learning. METHODS: A questionnaire distributed nationally during this period captured Radiographer opinion through the use of closed and open questions...

This review summarizes possibilities of including scientific methods for investigation of art objects into the secondary school chemistry curriculum. We discuss methods such as X-ray radiography, infrared reflectography, neutron activation autoradiography, X-ray fluorescence, and Raman spectroscopy and provide recent examples of their use. The results obtained, especially when combined with modern digital image processing algorithms, are indeed impressive. The second part of the paper is devoted to suggestions for actual use in teaching...

BACKGROUND: Repetition of an image is a critical event in any radiology department. When the repetition rate of routine digital chest radiographs is high, radiation exposure of staff and patients is increased. In addition, repetition consumes the equipment's life span, thus affecting the annual budget of the department. OBJECTIVE: The aim of this study is to determine the impact of a printed educational module on reducing the repetition rate of routine digital chest radiography among radiographers in Makkah Region tertiary hospitals...

BACKGROUND: Developmental dysplasia of the hip (DDH) is one of the prevalent musculoskeletal conditions in young adults and is a leading cause of hip osteoarthrosis in this age group. The optimum age for surgical intervention when needed is not well established in the literature and the lack of management guidelines and standard practice of DDH leads to different practices worldwide. This study aims to investigate the current practice of paediatric orthopaedic surgeons in diagnosing and treating DDH worldwide and identify points of agreement and disagreement...

In the period 2013-2016 the National Centre of Radiobiology and Radiation Protection (NCRRP) at the Ministry of Health of Bulgaria has developed a web based platform for performing national patient dose surveys and establishing Diagnostic Reference Levels (DRLs). It is accessible via internet browser, allowing the users to submit data remotely. Electronic questionnaires, specific for radiography, fluoroscopy, image guided interventional procedures, mammography and CT, were provided. Short and clear manuals were added to guide users and minimise human errors...

The main topic of the session is to show how dose optimization is being implemented in various regions of the world, including Europe, Australia, North America and other regions. A multi-national study conducted under International Atomic Energy Agency (IAEA) across more than 50 less resourced countries gave insight into patient radiation doses and safety practices in CT, mammography, radiography and interventional procedures, both for children and adults. An important outcome was the capability development on dose assessment and management...

INTRODUCTION: In pediatric spinal deformity the gold standard for curve surveillance remains standing full-column radiographs, but repeated exposure to ionizing radiation motivates us to look for nonradiographic solutions. This study tests a modern system of surface topography (ST) to determine whether it is reliable and reproducible. METHODS: Patients from 6 pediatric spinal deformity clinics were recruited for enrollment. Inclusion criteria were age 8-18; diagnosis of scoliosis measuring ≥10 and <50 degrees or increased kyphosis of ≥45 degrees...

OBJECTIVES: It is a big challenge to diagnose the motives behind trepanations in prehistoric crania. Surgical-therapeutic attempts may be apparent by the presence of fractures, however, ritual or nonmedical motives are rarely supported by visible evidence in the bones. This article presents data on the trepanations of several individuals from South Russia dating to the Eneolitic and Bronze Age that may indicate a ritual procedure. In these crania an operation was performed in the identical location, the midline, furthermore in one of the most dangerous places, on the obelion...

The purpose of this work was to develop a quantitative method for evaluating the pulmonary inflammatory process (PIP) through the computational analysis of chest radiography exams in posteroanterior (PA) and lateral views. The quantification procedure was applied to patients with tuberculosis (TB) as the motivating application.A study of high-resolution computed tomography (HRCT) examinations of patients with TB was developed to establish a relation between the inflammatory process and the signal difference-to-noise ratio (SDNR) measured in the PA projection...

IMPORTANCE: The National Lung Screening Trial (NLST) found a reduction in lung cancer mortality among participants screened with low-dose computed tomography vs chest radiography. In February 2015, Medicare announced its decision to cover annual lung screening for patients with a significant smoking history. These guidelines promote smoking cessation treatment as an adjunct to screening, but the frequency and effectiveness of clinician-delivered smoking cessation interventions delivered after lung screening are unknown...

INTRODUCTION: Lung screening is an opportunity for smoking cessation and relapse prevention, but smoking behaviors may differ across screening results. Changes in smoking were evaluated among 18 840 current and former smokers aged 55-74 scheduled to receive three annual lung screenings. METHODS: Participants were randomized to low-dose computed tomography or single-view chest radiography in the American College of Radiology/National Lung Screening Trial. Outcome measures included point and sustained (6-month) abstinence and motivation to quit among smokers; and relapse among smokers who quit during follow-up, recent quitters (quit < 6 months), and long-term former smokers (quit ≥ 6 months)...

Marco Marozzi
A class of multivariate tests for case-control studies with high-dimensional low sample size data and with complex dependence structure, which are common in medical imaging and molecular biology, is proposed. The tests can be applied when the number of variables is much larger than the number of subjects and when the underlying population distributions are heavy-tailed or skewed. As a motivating application, we consider a case-control study where phase-contrast cinematic cardiovascular magnetic resonance imaging has been used to compare many cardiovascular characteristics of young healthy smokers and young healthy non-smokers...
